gas chromatography interview questions General Introduction

Gas Chromatography is a popular separating and analyzing instrument which widely used to test a particular substance, or separating the different components. It is widely used in Petroleum, chemical, biochemistry, medicine, food industry, environmental protection and other aspects of a very wide application. gas chromatography interview questions can also used to prepare pure compounds from a mixed materials.

APEX gas chromatography interview questions Working Process

We will use a gas separator or a gas chromatography interview questions. The components will be separated by heating. A column is used to separating the components of a compound. This column is made of a narrow metal tube. It has a filling which is a microscopic layer of liquid. This is being referred to as the stationary step. The sample will be transported inside the column using the carrier gas which is usually helium, hydrogen or nitrogen. This is then referred to as the mobile or moving phase. The time and speed will also be monitored during the process.

The first stage is to set up the preparatory conditions. Set the parameters for the test that you want to process. These are the basic conditions that will be used, the condition include temperature, identified carrier gas, and the gas flow rate.The exact measurement of the narrow tube should be considered and prepared too.
